Wasn't the 3.7.10 regression only a problem on reboots if you used 
gluster snapshots? (which proxmox doesn't). I'm currently using 3.7.10, 
no issues with restarts so far.

Rats, I thought it was in 3.7.11 :( but can't it also be worked round by 
disabling "cluster.data-self-heal"? or was that something else.


I'm getting pretty good heal performance with the following settings:

- features.shard-block-size: 64MB
- cluster.self-heal-window-size: 1024
